Oil prices settled slightly higher on Friday to put up a fifth straight weekly gain for U.S. crude, as bullish comments from Russia contended with a resurgent dollar and a rising oil rig count.
U.S. West Texas Intermediate (WTI) crude settled up 22 cents higher at $50.85 a barrel, closing the week up 1 percent.
Global benchmark Brent crude futures rose 42 cents to $51.80 a barrel by 2:41 p.m. ET (1841 GMT). The contract is down about 0.3 percent for the week.
A closely watched report from oil services firm Baker Hughes showed the number of active U.S. oil rigs rose by 11 this week, the 17th week without a decline in the rig count.
The last time U.S. oil rigs rose by 10 or more was two months ago, when there were 15 additions in the week of Aug. 15 and 10 in the week of Aug. 19. U.S. crude prices then ranged between $44 and $48.
